SPECIFICATION forming part of Letters Patent No. 403,576, dated May 21,1889.

Application filed August 23, 1888. $erial No. 283,532. (No model.)

To all whom it may concern.-

Be it known that I, GURDON CONKLING, a citizen of the United States,residing at Glens Falls, in the county of \Varren and State of New York,have invented new and useful Improvements in Magnetic Separators, ofwhich the following is a specification.

This invention relates to a magnetic separator, as set forth in thefollowing specification and claims, and illustrated in the accompanyingdrawings, in which- Figure 1 is a section of a separator along the lineas as, Fig. 2. Fig. 2 is a plan view of a separator. Fig. 3 is asectional view of a modification. Fig. 4 is a sectional view of anothermodification.

Similar letters indicate corresponding parts.

In the drawings, the letter A indicates a conveyer or support for. themass to be treated, such as crushed or pulverized iron ore. A suitablesupply device-such as a hopper, B- can be used to feed the mass to theconveyer. A revolving disk, 0, is arranged between the mass undertreatment and a magnet, D. The magnet causes the magnetic particles-suchas iron-to adhere to the disk 0, which carries them to a hopper, whencethey pass into a suitable receptacle.

In the drawings are shown two magnets, D, two hoppers, E, and tworeceptacles, F. A receptacle, G, is shown for the non-magneticparticles. The two magnets may be of different intensities with relationto the mass under treatment. By having, for example, the magnet nearerto the hopper B of less relative intensity than the other magnet thefirst-named magnet can be made to cause only pure magnetic particles toadhere to the disk C, while the other magnet will then have a tendencyto cause magnetic particles, with other or non-magnetic substances, toadhere to said disk. A differential separation can thus be secured,perfectly pure magnetic particles being deposited in one receptacle Fand magn etio particles with other or non-magnetic substances beingdeposited in the other receptacle F.

The magnets D may be either permanent or electro'magnets, and theirdifferent intensities with relation to the mass under treatment may bevariously attained. For exam ple, by making one magnet weaker thananother and placing both magnets at an equal distance from the massunder treatment the action of one magnet on said mass will be weakerthan that of the other magnet; or by making both magnets of equalintensity and placing one magnet at a greater distance from the massunder treatment than the other magnet the action of one magnet on saidmass will be relatively weaker than that of the other magnet. The magnetof less rela tive intensity can be made to cause only pure magneticparticles to adhere to the disk 0, and the magnet of strong relativeintensity will then tend to cause magnetic particles, together withnon-magnetic particles, to adhere to said disk.

The conveyer A maybe variously formed as, for example, in Figs. 1 and 2,where the conveyer is a belt traveling over rollers, or, as in Fig. 3,where the conveyer is an incline which can be set at various angles, asrequired, or, as in Fig. 4, where the conveyer is a chute or tube,through which the mass falls.

The disk 0 can be rotated by any suitable well-known means, and byconnecting the disk 0 and the rollers of the conveyer A, Fig. 2, as bymeans of a belt, H, motion can be transmitted between the conveyer anddisk; or, the conveyer might be a stationary table, over which the massto be treated is spread in a suitable layer to be attracted by themagnet to the disk.

Whatl claim as new, and desire to secure by Letters Patent, is

1. The combination, with a conveyer for supporting the mass to betreated, of a magnet, a disk revolving independent of the conveyer andmagnet at a point between said conveyer and magnet, and means forrevolving the disk, substantially as described. i

2. The combination, with a conveyer for supporting the mass to betreated, of a stationary magnet, a disk revolving between the conveyerand the stationary magnet, and means for revolving the disk,substantially as described.

3. The combination, with a conveyer for supporting the mass to betreated, of a magnet located above the conveyer, a disk revolving abovethe conveyer and under the magnet, and means for revolving the disk,Intestimonywhereoflhavehereunto set my substantially as described. handand seal in the presence of two sub- 4.
